To all whom it may concern.

Be it known that I, GEORGE P. KLINE, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Metallic Compose t'ions, of which the following is a specification.

My invention relates to a new COHIPOFiliiOH of metals, designed more speciall for use in the construction of PlStOll-J'Ofl. packing, of that class for which Letters Patent of the. United States No. 723681 were issued to me March 24, 1903. This packing is intended for use in and about locomotives and other engines in. which the steam is used in a su perheated condition. For this purpose it is necessary that the composition shall he of such a quality that it will comply with certain requirements. It nulst: not he utl'ected by the high degree of temiierature which is possessed and imparted by said superheated steam; it must possess a suliicient degree of hardness to resist thefrictional action of other parts having movement thereon: and it must not be so hard as to cause an ahm sion of such movable parts.

hly composition coinprisvs copper. lead. and phosphorus. combined in substantially the following proportions. by weight. of the several ingredients, to wit: copper, eighty parts; lead, twenty parts; and phosphorus from one to two per cent. of the entirc compound. Thc several parts are combined a hilc in a molten state, and molded or othcrwise formed into members or pieces of a dored pattern.

taining the desired temper of the alloy of metalswhcn exposed to extreme degrees of heat, such as is possessed by superheated steam. T am aware that phosphorus has been made use of before in the formation of alloys of metals, but not in the propoc tions named herein, nor with the results which are derived therefrom. The use of more than two per cent. of phosphorus is found to be unsatisfactory, and renders the compound useless for thepnr 'iose for which it is: intended.

Any considerable variationuin the proportions of copper and lead also renders the composition unfit for use in superheated localities. although when used with saturated steam the proportions could be changed to sovent parts of cooper and thirty parts of lead, with proportional changes of such metals between said last named proportions and the proportions herein first set forth, to accord with varying steam pressures between the saturated and superheated con d itions.

hat I claim and tl'rs Patent, is

The herein described composition of matter consisting of copper. eight parts by weight. lead. twenty parts by Weight, and phosphorus not to exceed two per cent. by Weight of the total compound.

In testimony whereof I affix my signature in the presence of two witnesses.
